This is exactly why DIY pyrotechnics are never “harmless fun.” What looks like an urban celebration becomes a high-energy blast event in seconds. The overpressure, debris projection, and rapid smoke displacement tell you everything you need to know about the force involved. There’s no control, no buffer zone, and no second chance. This isn’t science. It’s uncontrolled ignition in a public environment. Footage shared for awareness—not entertainment. Learn the risk before you underestimate it. #ex
